Restore your engine’s performance with this direct-fit OE replacement knock sensor. Designed for easy installation, it uses a piezoelectric crystal to detect engine knock and send signals to the ECU. The ECU then adjusts ignition timing to prevent detonation, protecting your engine from damage and ensuring smooth operation.

Replacing a failed knock sensor restores proper ignition timing for optimal power, fuel efficiency, and long-term reliability. This sensor is engineered to meet or exceed OEM specifications, making it the perfect solution for maintaining peak engine performance.
